IMPRovED Doon-KNOB.

The Schedule referred tQ in these Letters Patent and making part of the same.

To all persons to whom these presents may come:

Be it knownthat I, GEORGE B. LoTHRoP, of Boston, ofthe county of Su'olk, and State of Massachusetts, have invented anew and' useful Improvement in Handlesor Knobs for Doors; and do hereby de`` clare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a side elevation,

Figure 2, a longitudinal section, and

Figure 3, a transverse section of a door-handle or knob, as made in accordance with my invention.

'This handle or knob has' a metallic shank, and a glass or mineral or vegetable bodyor head, the latter being extended throughtbe head of the latter.

In the drawingsI A denotes the metallic shank as ,provided with a tubular head or socket-piece, a.

This shank has a hole or passage, b, extended.

axially through it, and opening into the bore of the head.

The body or head B of the handle is' exhibited as formed at its middle v'to tit the bore of the head ,The said knob or head, when in place in the bore, usually projects in opposite directions therefrom, in

manner as represented, although it may extend iii one direction only therefrom.

Where projecting from the tubular head, the vb'ody maybe prismatic or have any other ornamentalshape or shapes.

There is made in that-part of the body which is within the tubular head or socket-piece a, a recess, c,

which is to be arranged to open into the bore or pasv sage b of the shank. n

A metal, in a molten state, is to be pouredinto the passage b, so as to ll the recess c, and extend therefrom into the said passage, such being as shownat e,

in Figure 4, whichiis a longitudinal section ofthe handle, as finished.

This metal serves to hold the glass body t6 the metallic shank.

' I claim the improved door-handle as made with itsvhead B and shank A, arranged as set forth, and with ,the

recess c in the head, and the passage-b irf the shank for the reception of a metal, e, when cast intO'them,

yas and for the-purposeset forth.
